Fastrax M0.5 21T Steel Pinion Gear (2.3mm)

The Fastrax M0.5 21T Steel Pinion Gear (2.3mm), part number FASTM5-21, is a fine-pitch RC pinion designed for M0.5 module gear trains. With 21 teeth and a 2.3mm bore, it provides a straightforward option when your setup requires this specific pitch, tooth count and shaft size. Its steel construction offers a robust drive interface when paired with an appropriate M0.5 spur.

For smooth, efficient running, ensure the module and tooth count match your spur gear and verify the bore suits your motor shaft. Correct gear mesh and alignment are essential to minimise wear.
